Another object o'l my invention is the conlructiou of a demountahle rim including a n svel and iin'lproved lot-long bolt, cmistructed kid arrarured so as to positively retain the aorta in position and 'l urther ali'ordiiug; a iositive means for setting the bolts circuml'crentially of the rim.

it further object of my invention is the construction of a 'dcn'muntable rim of the :hzss described. which is extremely simple in construction, hi ahly ellicient in operation and use, strong practical dun-able consisting of a n'rinimun'l number of parts and otherwise adapted to be 1nanu'liactin'ed at an extremely low cost, whereby its connnercial possibilities are greatly enhanced.

and grip the said tire as clearly shown by tl igure 2 of the dra Wings. lliveted or otherwise secured to the inner face of the rim 8 l have provided a plurality o't radial, substantially wide plates .10 which are l.i.-shaned. in cross cctiou. The plates l0 abut the outer side the and the lat portions thereof overlie the s eel rim l". l lalicndinu transve sely through the telly ii at dill'creil points on its circunilerence are tic sleeves Ill one end o t cash of which is provided with an enthe :icllv. lie h :0 receive the threaded portion l5) oil. a screw vheenlarged head loot which intends it a t angles to the main portion or stern of lie )UllJ" The head is formed with oimositely lisnm-ied cars or wings 1'3", 153, which torn icaringr surfaces for the locking nieui'u; sull-- seq uently to he referred to.

The inner portion oi? the plate 1.0 par tially cut away to interfi-t with a small am;- iliary plate 19, which secured to the telly on the outside thereof by the screws .ll scn'ii-circula aperture is formed in. the inner portion oil? the plate 10 which coope 'ates with a similar semi-circular aperture in the face of the auxiliary plate 19* to per-nut oi. the passage of the stem portion 22 oil? the bolt. in order to securely lock and. retain the bolt in position, the plate 10 is provided with an aperture which. adapted to re ceive the enlarged end 2 5i: ot a locking; pin 2:1 said pin passing; thi'iuug li an aperture in the central raised portion no ol the head Ill. ill substantially rectalwulal. cnlai'geiumlli 2i" at the opposite end oi: the pin and extendin; slightly beyond the .rnised portion 26 ot the head, permits the in to he moved out wardly against the r sistance oil? the spring 28 held on the pin and hearing; against the enlarged portion. or shoulder M as shown by Figure 4t of the drawings. The aised stop preferably formed integral with the plate 10 and indicated by numeral 30 and a second raised stop 31 preferably formed integral with the auxiliary plate 19 permits the properpositioning oi the head it in the locked and unlocked 'ioeition when it is desired to assemble the parts. The lcey 32 is provided with lugs 33 on. its lower end which are adaptml to ride beneath the on larnement 27, so that by hearing outwzn'dly on the wings 17, 3.8, the pin may he withdrawn from the aperture 23 and the head (ill till

n o l 16 rotated a halt turn to lock or unlock the rim. The stops 30 and 31 are so positioned that the head may be locked with certainty since the pin will fall in the slot 523 when the head 16 is turned.

My invention is particularly designed for use in connection with the type of demountable rim shown and described in my Patent Number 1,468,443, granted September 18, 1923.

\Vhile I have illustrated and described my invention with some degree of particula rit I realize that in practice Various alterations therein may be made. I therefore IOSOIYO the right and privilege of chang inn the form of the details of construction or otherwise altering the arrangement of the correlated parts Without departing:from the spirit of the intention or the scope oi the appended claims.

Having thus described my invention What I claim as new and desire to secure by United States Letters Patent is 1 1. The combination rith den'iountable rim and a wheel telly, of a plurality of sub- 5 antially wide plates attached to said rim and abutting the outer side of the telly, a sleeve for each of the plates extending;- through the telly locking bolts having enlarged heads for the SlGGYOS, said plates having apertures, and releasable means carried by the bolt heads cooperating with the apertures for locking the said bolts to the plate.

2. The combination with a demountable rim and a Wheel telly, of a plurality of substantially Wide plates atta lied to said rim and abutting the outer side of the telly. a. threaded sleeve for each of the plates extending through the lelly. a threaded lOCling' bolt in each sleeve havingan enlarged head formed thereon. said plates having apertures and spring held pins carried by ach of the bolt heads and adapted to enter the apertures whereby the said bolts are locked to the plate.

3. The combination with a dcnnaiutable rim and a wheel ilelly. ol plurality ol. substantially wide L-shaped plates attached to the rim and abutting the outer side ol the 'l clly. a threaded sleeve torincd with each oi? the dates extending through the telly. a bolt having an enlarged head for each ol the sleeves. said plates having apertures, spring held pins carried by the bolt heads cooperating); with the apertures l'or lot-hing the bolt heads to the plates and stops on the face of said plates for guiding the bolt heads into locking position.
